I did somewhere say I wanted nothing on this site to trigger any net nanny software.

I think perhaps net nanny software looks for keywords and not context or association so sensible discussion may be trapped - perhaps rightly.

Important committees have been reporting on definitions and degrees of murder...

I was involved in some consultations with a variety of people at universities earlier this year. i was listened to the concerns of people at a joint Newcastle upon Tyne and Durham university meeting and without prompting they identified spiked drinks as their major worry.

This raises the question of motivation in sex crimes.

Whatever may be said about certain acts they are clearly not aimed at getting anybody pregnant.

When one tribe invades the village of another tribe they are apt to use rape as an act of war. When they do they are trying to dominate the invaded tribe but also trying to ensure that as many of the individuals born into the next generation in that rival village have natural fathers in the invading tribe as possible - colonisation through the cradle.

We often use words in imaginative ways. We may consider the erection of Mock Tudor Mansions in beautiful countryside as the Rape of our Natural Heritage. We are using the term rape here to mean despoilment.

Thus in sex crime we have a tendency to refer to a whole range of acts as rape. Generally, except in the 'he looked at me funny' extreme case of psychological rape, we do tend to mean penetrative sexual assault when we say rape.

However, the date rape drugs do bring back the prospect of 'urban' tribal rape.

The scenario is that a man spikes a woman's drink and then not only has sex with her whilst she is powerless to resist, he has sex with her whilst she id powerless to know and he then arranges things so that she wakes not knowing that she has had sex and not knowing that she should make a complaint and not knowing that she is in 'need' of the morning after pill.

This is suggested as the leading reason for the use of the routine contraceptive pill in 16 to 24 year olds rising fro around 12 per cent to around 24 per cent - figures not exact - in the period of the rise of general public awareness of the potential of date rape drugs.

It is currently being properly researched but the effect is already there and the idea behind it is that women generally believe that no matter how drunk they were the night before they would remember if they had had sex but they are not at all sure they would remember if their drink had been spiked.

Two things emerge.

Firstly women are beginning to loose faith in the morning after pill because they begin to doubt they would know when to take it.

Secondly, there is growing evidence of a need to distinguish in law between a criminal intent to have sex without consent and a criminal intent to procure a pregnancy without consent.
